And while already qualified for the knockout stages, they were brought back down to earth with a bump in Salford as they lost 38-5.
The Dragons were already trailing 24-0 at half-time and while Ashton Hewitt scored a late consolation, it did little to lift the spirit of Jones.
Their next outing will be a GUINNESS PRO12 clash with Leinster in a week's time and Dragons head coach Jones is keen to see some improvements.
"It's fair to say it was a shocking night for us and we are disappointed with the standard of performance," explained Jones.
"Fair play to Sale, they were excellent and everything they touched turned to gold. You get good days and bad days in rugby and it wasn't a very good one for us. We are a better side than what we put out there.
"We have played so well in this competition so it's disappointing to finish off on such a negative in front of the world. The good of the campaign dissipates.
"The motivation was in the Sale changing room because they were fighting at home to win the group and we didn't show up mentally and that showed in the first half.
"We put 30 points on Castres one week and concede 30 the next, that's not the consistency that any coach or player is proud of."
